Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to a container quay crane. Background Art

[0002] Container quay cranes (also called container cranes or port cranes) are important equipment for loading and unloading containers at ports. They are usually used to unload containers from ships or load containers onto ships. The introduction of remote operation technology makes the operation of these equipment safer and more efficient.

[0003] Structural composition: Lifting arm: with a long arm span, able to cover ships and docks. Hook and grabber: used to grab and move containers, usually equipped with intelligent identification system. Mobile chassis: can move on the track to adapt to the loading and unloading needs of different ships. Control system: equipped with remote control and monitoring system to realize the operation and monitoring of the crane.

[0004] The remote crane is connected to the operator's console via radio or the Internet, and the operator can operate it from a safe distance.

[0020] like Figure 4 As shown, an oil drain pipe 501 is fixedly connected to the bottom end of the steel cable pretreatment seat 5, a rotating ring 502 is rotatably connected inside the steel cable pretreatment seat 5, and a plurality of rollers 503 are rotatably connected to the inner wall of the outer side of the rotating ring 502, and the rollers 503 are in sliding contact with the inner wall of the steel cable pretreatment seat 5.

[0021] Two steel cable scrapers 504 are symmetrically arranged in sliding cooperation in the rotating ring 502. The steel cable scrapers 504 are adapted to the outer wall of the steel cable connected to the winch 3. The inner end of the steel cable scraper 504 is connected and fixedly arranged with an electric push rod 505. The electric push rod 505 is connected and fixedly arranged with the inner wall of the rotating ring 502. The electric push rod 505 drives the steel cable scraper 504 to be stuck on the outer wall of the steel cable. Then, when the winch 3 winds up the steel cable, the steel cable scraper 504 will be driven by the spiral structure of the outer wall of the steel cable to make the rotating ring 502 rotate, clean the old lubricant on the outer wall of the steel cable, drop it into the steel cable pretreatment seat 5, and discharge it through the drain pipe 501.

[0022] like Figure 6As shown, both ends of the cover plate 7 are provided with an inclined slide groove 701, and a push rod 702 is provided on the inner wall of the inclined slide groove 701 for sliding cooperation. The other end of the push rod 702 is connected and fixedly provided with a contact slide rod 703, and the contact slide rod 703 is provided with a sliding cooperation arrangement penetrating the inner wall of the lubricating oil seat 6, and a spring 704 is connected and fixedly provided on the contact slide rod 703, and the other end of the spring 704 is connected and fixedly provided with the inner wall of the lubricating oil seat 6, and the bottom end of the contact slide rod 703 is provided with a movable contact arrangement with the fixed seat 4. The lubricating oil seat 6 is driven upward by the hydraulic cylinder 602, and the contact slide rod 703 is not in contact with the fixed seat 4 at this time. At this time, under the action of the spring 704, the contact slide rod 703 is driven to move downward, thereby driving the connected push rod 702 to move downward, so that the other end of the push rod 702 slides in the inclined slide groove 701, thereby driving the cover plate 7 to move away, so that the lubricating oil seat 6 can be sleeved on the outside of the steel cable.

[0023] like Figure 8 As shown, the transmission mechanism 9 includes a rotating sleeve 901, which is rotatably connected to the inner wall of the lubricating oil seat 6, and a motor 902 is fixedly connected to the outer end of the rotating sleeve 901. The motor 902 is fixedly connected to the outer wall of the lubricating oil seat 6, and a transmission wheel 903 is fixedly connected to the outer wall of the inner end of the rotating sleeve 901, and the transmission wheel 903 is meshed with the arc-shaped rack 802 for transmission.

[0024] A rotating rod 904 is slidably arranged on the inner wall of the inner end of the rotating sleeve 901, and the other end of the rotating rod 904 is rotatably connected to the moving seat 803. An incomplete bevel gear 905 is fixedly arranged on one end of the rotating rod 904, and two bevel gears 906 are movably engaged and transmitted on one side of the incomplete bevel gear 905.

[0025] A rotating shaft 907 is fixedly connected between the two bevel gears 906, and the rotating shaft 907 is rotatably connected to the moving seat 803. An adjusting gear 908 is fixedly connected to the bottom of the rotating shaft 907, and the adjusting gear 908 is meshed with the fixed rack 604 for transmission. When the rotating sleeve 901 rotates, the incomplete bevel gear 905 connected to the rotating rod 904 is driven to rotate, so that the incomplete bevel gear 905 is meshed with the two bevel gears 906 in sequence, thereby driving the connected rotating shaft 907 to rotate forward and reverse, so that the adjusting gear 908, under the action of the fixed rack 604, drives the moving seat 803 to move back and forth quickly.

[0026] Working principle: During the use of the container quay crane, when the lifting cable needs to be maintained and lubricated, the electric push rod 505 is first used to drive the cable scraper 504 to be stuck on the outer wall of the cable. Then, when the winch 3 reels the cable, the cable scraper 504 will be driven by the spiral structure of the outer wall of the cable to make the rotating ring 502 rotate, clean the old lubricating oil on the outer wall of the cable, drop it into the cable pretreatment seat 5, and discharge it through the oil drain pipe 501; Then, the hydraulic cylinder 602 is used to drive the lubricating oil seat 6 to move upward. At this time, the contact slide bar 703 is not in contact with the fixed seat 4. At this time, under the action of the spring 704, the contact slide bar 703 is driven to move downward, thereby driving the connected push rod 702 to move downward, so that the other end of the push rod 702 slides in the inclined slide groove 701, thereby driving the cover plate 7 to move away, so that the lubricating oil seat 6 can be sleeved on the outside of the steel cable; Then, a proper amount of lubricating oil is injected into the lubricating oil seat 6 through the oil filling hose 601, and then the motor 902 is used to drive the rotating sleeve 901 to rotate forward and reversely, so that the rotating sleeve 901 drives the connected transmission wheel 903 to rotate, so that the transmission wheel 903 drives the brush oil ring 8 connected to the arc-shaped rack 802 to reciprocate, so that the brush plate 801 on the brush oil ring 8 evenly brushes the lubricating oil on the steel cable; At the same time, when the rotating sleeve 901 rotates, it will drive the incomplete bevel gear 905 connected to the rotating rod 904 to rotate, so that the incomplete bevel gear 905 will mesh with the two bevel gears 906 in turn, thereby driving the connected rotating shaft 907 to rotate forward and reverse, so that the adjusting gear 908, under the action of the fixed rack 604, will drive the moving seat 803 to move back and forth rapidly, so that the brush plate 801 can further brush the lubricating oil evenly on the steel cable.
